The chandelier is a set of single-lamp fixtures assembled in one original design. It is not only a decoration of the room, but also a powerful source of lighting. The maximum mode of operation of the chandelier is not used as often (mainly - at family celebrations, etc.). Most of the time, the lamp operates in an economical mode (when not all lamps are turned on, but only part of them), while the level of illumination does not cause a person's discomfort. Operation modes are controlled by a double switch.
Connection diagram when the switch is installed
Next, consider how to connect a chandelier to a double switch. How is the electrical circuit of the lamp assembled? The knowledge of elementary fundamentals will provide an opportunity to better understand how to connect a chandelier to a double switch. So, the scheme. As a rule, three wires come out of the chandelier. One of them has a black color - this is a zero working wire. It is attached to the threaded parts (side lobes) of all cartridges. The other two wires are phase conductors that are connected to the central contacts (tongues) of the cartridges, each to its own group. Sometimes the fourth wire, painted in yellow with green stripes, also appears - this is a protective conductor. It is attached to the metal parts of the lamp. How to connect a chandelier to a double switch if it is already installed? In this situation, it remains to connect the wires coming out of the chandelier with the conductors coming out of the ceiling. In this case, it is necessary to determine the phase and zero working conductors to which the lamp will be connected. Phase conductors can be detected using a voltage indicator. To do this, turn on both keys of the switch and check for voltage on the wires leaving the ceiling. On two wires the indicator will show the presence of voltage, on the third - absence. This third is the zero worker. It connects to the neutral conductor of the chandelier (black). Two phase wires are connected to the phase wires of the chandelier in any order. The connection must be made using a terminal block or terminal block on the terminals.
Circuit breaker installation
How to connect a chandelier to a double switch, if it is not already installed? Usually three wires are connected to the place of its installation. Voltage is applied through one wire, and the other two are connected to the chandelier. The switch itself has three terminal connections. One of them is common, and the other two using the keys are turned off or connected to the common. The wire through which the voltage (phase) is applied to the switch is connected to the common contact (it is determined using the voltage indicator). The other two wires are to the remaining terminals of the switch in any order.
What to do if extra wire is needed
It often happens that only two wires are suitable for a chandelier and a switch (usually such wiring exists in old buildings). In this case, a reasonable question arises about how to connect the chandelier to a double switch in this situation. To do this, simply extend the additional wire between the switch and the chandelier. It should have a cross section no less than that of existing wires.
If necessary, you can connect the chandelier to two single-key switches. How to connect a chandelier to two switches, you can easily understand by studying the above material. In this case, the incoming phase conductor is connected by a loop to the contact of the second switch.
Connecting the chandelier to a double switch or just a switch requires safety measures. To do this, disconnect the voltage from the place of work.
